Panasonic Bridge Camera - bought before my DSLR - mostly used by the wife, but I use it when on Business travel.Iphone if I have to...Otherwise it's film cameras very occasionally - Pentax, Chinon, Olympus PENs...

I'm a chemical engineer, and I use my iPhone multiple times a week to take pictures out in the field for documentation. I have 2 Canon compact cameras that are used seldomly (one I just keep around because I have an underwater case for it), and one Nikon D70s body I use to test Nikkor lenses that I occasionally fix. I've often looked for good used deals on Panasonic GF series and Olympus E-PL series cameras for a small, light camera to carry, but never jumped on anything I've found (Nikon 1 sensor is too small, as is its selection of third party lenses currently, and I'm not a big fan of the NEX cameras, since they don't have a truly compact zoom like the Panasonic 14-42mm PZ).

I've recently acquired a Sony NEX-6 because I wanted to get a good (APS-C) compact system camera and Canon isn't quite there, yet. The last few years I've been pretty loyal to Canon, until now.

What other camera brand do you actively use, other than Canon? If you like, please specify which model and why.

Nikon D7000 & Nikkor 18-300mm VR lens ... I find this combo to be very versatile covering the fov of 3 lenses in 1 ... since last Saturday my office bag (LowePro Event Messenger 250) always has the Nikon D7000 + 18-300 VR lens, Yonguno YN569EX, Better Beamer, Mac Book Pro, iPad Mini, iPhone and the CamRanger. With this set up I pretty much have almost everything I need for general use and it is not very heavy. But the camera I really use the most has to be my iPhone 4S ... although I don't use it much for "real" photography, it is used several times a day for saving receipts, bills, screen shots, serial numbers, articles/addresses/maps/adverts published in news papers & magazines etc just to mention a few Of course, for all "serious" photography it is back to Canon 5D MK III, few L lenses & a couple of 600 EX-RTs.
